What to do if you discover a lump?

Dr. Greene’s advice on discovering a lump…

Finding a lump on your child’s body is not necessarily a bad thing, in fact most of the time little lumps it’s a good thing: healthy lymph nodes swell when they are attacking foreign invaders.

The question is how to tell if the lump is well-behaving lymph node or something more serious.

With just a couple of quick checks, you can either quickly rule out anything serious, or know that you and you child should follow-up with a doctor.

Watch the video below tell you how to determine which you’re dealing with.

If there is anything you’d like to know about lumps or lymph nodes that I didn’t address in the video, drop me a comment and I’ll try and shed some light on your question.

Dear, Dr.greene I’m 12 years old and frightened I fell asleep and woke up with a lump on my back/neck and I’m really scared

Hi Victoria,
Thanks so much for writing in! If the lump is still there and you’re feeling scared, it’s probably wise to first take some deep breaths and calm your body down, then tell an adult and/or go see your doctor. They can help.
Hope that helps, hang in there!

Doctor I discovered a painless lump in my 10 year old’s right armpit. We had X-rays and CBC blood work. All was considered normal. Although the radiologist did say on the report that there was a soft tissue lump seen. It has been there for at least 3 weeks. It doesn’t move, doesn’t hurt and has gotten slightly bigger. Should I be worried?

Hi I’ve just got my son back to sleep after a couple of hours pain out of nowhere I feel a lump it seems to move unless it’s because my child is agitated an moving I rub I console but I’m really scared this as been since he was a young boy around 12months but I put it down to growing pains or gristle I think it’s called why is it hurting ? Should I be scared he is now four years old .

My 14 year old daughter has a small painful lump on the back of her neck to the right of her spine. It came on suddenly. It hurts to touch. Should I keep an eye on it to see if it gets bigger. I don’t want her to be in pain. I thought maybe a warm moist compress in case it could be a pimple.

Hey am 17 and i recently had a sore throat this week and I notice this lump the Same week. Should I be worry about it. Please reply back as soon as possible

Bump head that left a lump

Hi Doctor Greene, My son is 15 years old and tonight he showed me 3 lumps on his neck below his ear, that were not there before. I have never noticed anyting like this before during his growing years. Should i be worried, have made an appointment to see his doctor.

I have this small movable lump in my breast not very sore to the touch but can be iritating,I don’t k ow if it was just me but I felt as if it had grown a tiny bit.If I move it to much it has a tingle on my nipple,I am only 14 years old I just want to know if it’s nothing to worry about as I have my full thought on cancer bug my parents say it’s probably not and booked me in for a doctors apointment.I juast need someone to explain this to me please


Dr. Greene outlines when to worry about breast lumps in boys. Here they are:

  • If they begin before age 10 years or after age 15 years (especially after puberty is complete)
  • If they are not directly under the nipple
  • If there is overlying dimpling of the skin, skin ulceration, or change in the color of the skin
  • If the they feel fixed to the skin
  • If they are large–over 1.5 inches (4 cm) in diameter
  • If they don’t go away within 2 years
  • If the nipples leak milk, blood, pus, or other fluid
  • If there are other signs of disease–night sweats, fever, or weight loss, for example

From your description, it doesn’t sound like any of these apply to you. I think it’s great your parents are taking you to see your doctor, in order to ease your mind. In the meantime, you can relax.

I started off having lower back pains on the left side it has now turned into a small squishy ball and seems like he kind of wants to roll around is really sore to touch what can I do or what could it be


I’m not a doctor, so I can’t tell you for sure (and probably a doctor couldn’t without examining you), but it sounds like a cyst I once had. It was surgically removed in an easy outpatient procedure with no side effects and no recurrence.

Bottom line, time to see your doc.

My 4 yr old has a couple of lumps probably just under 1cm diameter on his penis just under the skin….they seem soft and move around a bit..Doesn’t seem to be hurting him or causing any thing unusual .

Hey Doc my son is 6 months today. Last week I noticed he have’s like four lumps each side of the head and neck in different sizes what could it be. I have an appointment with the Doc in about 2 weeks should I take him sooner ??

That’s normal, all my children have had their lymph nodes like that and you can call your Dr office but I bdoubt they will have u come in.

Hello Doctor my son is 17 he has a bump on his back near his neck little fine bumps are on them he says the lump doesn’t hurt him he does play football….

Hey doctor.. Im 19 and recently i found a bump on my head.. Its in the middle its kinda bonny.
Should I get a visit about it?

My 4 month old grandson has had a hard lump about inch in diameter for over a month. The pediatrician says it’s a lymph node, but I am concerned because the lump is hard, doesn’t move and is not getting smaller. He is not sick and had no cuts. My daughter is taking him to a specialists next week. What tests will they do and if it is more serious how will they treat in?

Hi I’m 13 years old and I have a soft tiny bump in the middle of my back head and I’m really worried idk Wat to do please answer.

Hi I’m 13 and have a very soft moveable lump under my arm well it looks like a lump but doesn’t feel like it it sticks out and is sometimes painful it isn’t hard and it isnt non- moveable ! It’s very soft and moveable and sometimes becomes inflamed and itches !! I haven’t had any breast cancer symptoms and it isn’t getting any bigger and has gone down a bit I’ve had it for about 1 month and a half now I just wanted to ask you if it could be dangerous and if it can just be left alone !


If you’ve had a lump for longer than a few weeks, it’s worth a call to your doctor to discuss this with the advice nurse. He or she will know if your doctor would like to take or look just to be on the safe side.


Hi DR Green my daughter is 5yr old my wife found 2 lumps in her neck 1 round circle about 1cm diamiter the other lower very tiny both on her left side.she had a rash like flu a couple of weeks ago.As parents we are scared Sind her older sister 11 just went threw the same thing she had a lump under her armpit & a couple tiny 1s in her neck it tuned out to be Hodkins Lymphoma she was in stage 2 she went through chemo & know she’s been in remission for 2 months.so you see our worry Dr.Please write me back I’m at a loss.


When you have a child with a cancer diagnosis, it’s only natural to worry that a lump may be cancer. That doesn’t mean that it’s a problem, but your worry is understandable. If for no other reason than to ease your mind, it would be wise to have a doctor examine your 5 year old.

I hope that’s helpful,

My daughter has a hard pea sized “knot” even with her ear canal at the base of her skull. It is stationary and very hard. She’s shown none of the other symptoms you described in the video and acts fine. Should I be concerned?

Hi Dr. Greene….I really appreciate your video it was really helpful. I am a very concerned parent/grandparent, as last night a discover three lumps on my 12 year old granddaughter. One is walnut size located on the top of her neck, spin area and is hard and walnut in size, the other is behind her ear, also hard, not as big and then further down her neck, a pea size lump which seems to have some movement. The other two are solid in place. I have managed to get her into her doctor today; however, I am very concerned. Jan Ross

Hi Dr Greene…My 20 month old granddaughter is on of identical twins that were born prematurely at 37 weeks and she is the smaller of the two..She recently had roseola in which she had a high fever resulting in a convoltion..We took her to the hospital and she was released that night..That was 5 days ago..She now has 2 lumps in the back of her neck which are soft & movable and they don’t seem to be sore..Is this a concern?

H, I have a 4 month old baby girl & about a month or so ago we noticed a lump under her chin, it also looks bruised! It has gotten smaller & I thought it had gone away! Then there it was again, about the size of a nickle..it makes her look like she has a double chin! It doesn’t seem to bother her at all, she is a happy & active baby! She was born 6 weeks early & spent 12 days in the NICU because of low blood sugars,low weight & jaundice.. Anyhow, the lump is starting to worry me! Want to know if you have any ideas as to what it could be?!?! Thanks for your time (:
